1 Samuel 10:11

Is Saul also among the prophets? A man never instructed, nor exercised in, nor inclined to these matters. It begat wonder in all those who knew his education, that he should, on a sudden, be inspired as those were, who were bred up in the school of the prophets. For, though it was in the power of God alone to bestow the gift of prophecy upon men, yet it would seem that commonly he endowed none with it, but such as were trained up in those studies which might dispose them for it.
